As the struggle deepened yesterday to name the new baby born of the NYSE Euronext-Deutsche Boerse merger, one choice rang loudly — it’s got to have “New York” in it.

The two companies announced yesterday they had agreed to a $10.2 billion merger that would have the German exchange owning 60 percent of the combined company — which would be the largest owner of equities and derivatives markets in the world.

The new company, which has not yet been named, is expected to be incorporated in Amsterdam. It will own exchanges on Wall Street, and in Germany, France, Britain, Amsterdam, Portugal and Belgium and have joint headquarters in Manhattan and in suburban Frankfurt.

The deal could set off a wave of exchange mergers as companies maneuver to survive in a sector where more and more trades are handled electronically.

Under the deal, the German parent will get 10 of the 17 board seats in the new entity, with each share of NYSE Euronext swapped for 0.47 share of the new entity.

Officials involved in the deal said local exchanges would run under their recognized names.

Shareholders of the two companies and numerous regulators must approve the deal. Both companies said they hoped to close the deal by Dec. 31.

“This merger isn’t a quick turnaround. It’s going to face regulatory scrutiny and potentially political scrutiny and maybe some political backlash,” said Hank Smith, portfolio chief at The Haverford Trust Co.
